# OCR Plugin for Cthulhu Screen Reader
A powerful OCR (Optical Character Recognition) plugin that enables Cthulhu users to extract text from visual content including windows, desktop areas, and clipboard images. Originally based on the ocrdesktop project by Chrys, this plugin integrates seamlessly with Cthulhu's accessibility framework.
A powerful OCR (Optical Character Recognition) plugin that enables Cthulhu users to extract text from visual content and interact with it through precise coordinate mapping. Originally based on the ocrdesktop project by Chrys, this plugin has been enhanced with interactive features and comprehensive settings integration.
## Features
### 🔍 **OCR Operations**
- **Window OCR**: Extract text from the currently active window
- **Desktop OCR**: Extract text from the entire desktop screen
- **Clipboard OCR**: Extract text from images copied to the clipboard
- **Voice Announcements**: Clear audio feedback about OCR operations
- **Multi-threading**: Non-blocking OCR processing with progress tracking
- **Text Cleanup**: Automatic post-processing to improve OCR text quality
- **Interactive OCR**: OCR with coordinate mapping for clicking and navigation
### 🎯 **Interactive Coordinate Mapping**
- **Precise Clicking**: Click any text found in OCR results using exact coordinates
- **Dual View Modes**: Toggle between text view and interactive coordinate table
- **Safety Confirmation**: Preview click coordinates before executing
- **Real-time Navigation**: Browse OCR results and click immediately
### ⚙️ **Comprehensive Settings**
- **Language Configuration**: Support for all Tesseract language packs
- **Image Processing**: Grayscale, invert, black/white, and scaling options
- **Clipboard Integration**: Automatic copying of OCR results to clipboard
- **Quality Tuning**: Adjustable parameters for optimal OCR accuracy
### 🖥️ **Accessibility Integration**
- **Voice Announcements**: Clear audio feedback for all operations
- **Keyboard Navigation**: Full keyboard control of interactive features
- **Settings GUI**: Integrated settings tab in Cthulhu preferences
- **Non-blocking Processing**: Multi-threaded operation with progress tracking

- Wait for processing to complete
- OCR results will be announced via speech
3. **Best Practices**:
3. **Interactive OCR Workflow**:
- Press `Cthulhu+Control+F` to open OCR results window
- Wait for "Performing OCR on window for interactive results"
- Use `Alt+V` to toggle between text and coordinate table views
- Navigate with arrow keys in table view to find desired text
- Press `Enter` to click on the selected text location
- Confirm the click action in the safety dialog
4. **Best Practices**:
- Ensure good contrast between text and background for better results
- Use window OCR for focused content (faster processing)
- Use desktop OCR for content spanning multiple windows
- Use clipboard OCR for images from web browsers or image viewers
- Enable "Copy Results to Clipboard" for easy text retrieval
- Adjust scale factor for small or blurry text (try 5-7)
## Configuration
### OCR Settings
The plugin uses the following default settings (configurable in plugin.py):
### OCR Settings GUI
Access comprehensive OCR settings through Cthulhu Preferences:
```python
self._languageCode = 'eng' # Tesseract language code
self._scaleFactor = 3 # Image scaling for better OCR
self._grayscaleImg = False # Convert to grayscale
self._invertImg = False # Invert image colors
self._blackWhiteImg = False # Convert to black/white
self._blackWhiteImgValue = 200 # B/W threshold value
```
1. **Open Cthulhu Preferences**: `~/.local/bin/cthulhu -s`
2. **Navigate to OCR Tab**: Use keyboard navigation to find the OCR settings tab
3. **Configure Settings**: Adjust all OCR parameters through the accessible interface
### Changing OCR Language
To change the default OCR language, modify `self._languageCode` in the plugin's `__init__` method:
### Available Settings
```python
# Examples:
self._languageCode = 'fra' # French
self._languageCode = 'deu' # German
self._languageCode = 'spa' # Spanish
#### **Language Configuration**
- **Language Code**: Tesseract language pack to use (default: 'eng')
- Examples: 'fra' (French), 'deu' (German), 'spa' (Spanish)
- Use '+' for multiple languages: 'eng+fra' for English and French
#### **Image Processing**
- **Scale Factor**: Image scaling multiplier (1-10, default: 3)
- Higher values improve OCR accuracy for small text
- Lower values process faster but may miss details
- **Grayscale Image**: Convert to grayscale for better text recognition
- **Invert Image**: Invert colors (useful for white text on dark backgrounds)
- **Black and White Image**: Convert to pure black/white with threshold
- **Black/White Threshold**: Threshold value for black/white conversion (0-255, default: 200)
#### **Advanced Features**
- **Analyze Colors**: Extract color information from OCR regions (requires scipy/webcolors)
- **Copy Results to Clipboard**: Automatically copy all OCR results to system clipboard
### Configuration File
Settings are automatically stored in Cthulhu's configuration system:
- **Global Settings**: `~/.local/share/cthulhu/user-settings.conf`
- **Profile Settings**: `~/.local/share/cthulhu/app-settings/[profile]/`
### Example Configuration Values
```json
{
"ocrLanguageCode": "eng",
"ocrScaleFactor": 3,
"ocrGrayscaleImg": false,
"ocrInvertImg": false,
"ocrBlackWhiteImg": false,
"ocrBlackWhiteImgValue": 200,
"ocrColorCalculation": false,
"ocrCopyToClipboard": true
}
```
## Troubleshooting
@@ -127,6 +187,28 @@ self._languageCode = 'spa' # Spanish
- Test other Cthulhu speech functions
- Verify audio system is working
#### Interactive OCR window doesn't open
- **Cause**: GTK dependencies missing or display issues
- **Solutions**:
- Ensure GTK3 development packages are installed
- Check display/Wayland/X11 compatibility
- Verify Cthulhu GUI components are working
#### Click coordinates are inaccurate
- **Cause**: Window movement, scaling, or coordinate calculation errors
- **Solutions**:
- Ensure window hasn't moved since OCR capture
- Try recapturing with `Cthulhu+Control+F`
- Check display scaling settings
- Verify no window decoration changes occurred
#### Clipboard copy not working
- **Cause**: Clipboard setting disabled or GTK clipboard issues
- **Solutions**:
- Enable "Copy Results to Clipboard" in OCR settings
- Test clipboard functionality with other applications
- Check GTK clipboard permissions
